IMPROVEMENT IN WATER-METER DIALS.

Specification forming part of Letters Patent No. 175,523, dated March28, 1876; application filed January 17, 1876.

To all whom t may concern:

Be it known that I, DE WITT C. TAYLOR, ot' Brooklyn, in the county ofKings and State ot' New York, have invented a new and useful 1mprovement in l/Vater-Meters, of which the following is a specicationFigure l is a vertical central section of that part of a water-meterwhich contains my invention. Fig. 2 is a top view of the same; and Fig.3 a vertical section of a modification.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention has for its object to prevent the accumulation ofimpurities on the dial of a water-meter.

The invention has reference to those 'watermeter dials that arecontained Within the meter-shells, and therefore, during operation,immersed' in the water that passes through the meters. They haveheretofore been held stationary, and used in connection with rotatingpointers or fingers, which'- connect with mechanism that is moved by thewater that passes through the meters. All water carries more or lessimpurities, and deposits the same on its way, and the stationarywater-meter dials have, therefore, frequently been obliterated by suchsettlements, so that the iigures or marks upon them could not be readilydiscerned.

My invention consists, first, in mounting the submerged dial of awater-meter upon the revolving mechanism and combining it with astationary pointer, so that the dial,

by rotating, will prevent the accumulation of sediments; secondly, inperfor-ating said submerged dia-l to produce miniature currents thatwill wash the dial, and to prevent the obliteration of the ligures onthe dial; and, thirdly, in providing the pointer of the water-meter witha wiper, which will wipe thefigured part of the dial and keep it clean.

In the drawing, the letter A represents the dial-plate of a water-meter,the same being made of sheet metal or other proper material of circularor equivalent form. It is located within the body of the metershell Blbeneath a glass pane, O, .which is inserted and fastened in au openingof the metershell. D is the pointer or finger, which I secure rigidly tothe shell of the meter, or to an arm projecting therefrom.

The dial-plate A is connected with, and i mounted upon, the spindle E,to which rotary motion is imparted by the Water that passes through themeter, the water striking suitable wings or devices, which, in turning,cause the spindle E to turn, and with it the dial. By thus moving' thedial A beneath the stationary pointer the accumulation of impurities onthe dial will be prevented, as the motion of the dial prevents theirsettling.

The numerals b b, instead ot' being marked upon the dial by paint or inrelief, I propose to form by pert'orations through the dial, as shown,and the impurities, even if theyishould be allowed to settle on thedial, can thus never obliterate the numerals, but pass th rough Y them.

The dial may, however, also be perforated at other places. In fact, theperforated dial has the additional advantage of causing' small currentswhich will wash its surface.

The improved perforated dial Will also be useful when stationary under arevolving pointer.

When desired, .and for greater certainty of cleanliness, I propose toattach a wiper, a, in form ot' a sponge or pad to the under side ot' thepointer or index-hand, as shown in Fig. 3, said wiper to come in contactwith that part ofthe surface ofthe dial which it is necessary to keepclean.

This wiper may be used on all meters, those having stationary dialsunder rotary pointers aswell as those having stationary pointers aboverotary dials.

I claim as my inventionl. In a water-meter, the combination of thesubmerged revolving dial A with the rotating spindle E and submergedoperating mechanism, and with the stationary index or pointer D, allarranged so that the dial will be washed and cleaned by the current ot'water produced by the revolving motion of the dial.

2. In a water-meter, the submerged dial A, perforated to prevent theaccumulation of impurities, substantially as specified.

3. The combination of the index-hand or pointer D, and of the Wiper a,with the submerged dial A of a watermeter, substantially as specified.
